FIREARM.

SPECIFICATION forming part of Letters Patent No. 717,958, dated January6, 1903. Application filed September 13. 1899. Serial Fn. 730,358. (Nomodel To all w/eom, it nto/.y con/cern:

Be it known that I, JOSEPH C. WHITE, of Chelsea, in the county of Suiolkand State of Massachusetts, have invented a new and useful Improvementin Firearms, of which the following is a specification.

Myinventionis animprovement'on the com,- bined pistol and knifedescribed in my Patent No. 626,472, dated June 6, 1899; and it consistsin a novel lock and novel means for cocking the gun, as fully describedbelow and specifically claimed,

Figure l is an elevation, partly in section, of one form of myinvention. Fig. 2 is an edge View ofthe article shown in Fig. l. Fig. 3shows thetrigger detached. Fig. 4 is a detail ot the firing-plunger.4Fig. 5 is a section on line 5 5 of Figs. l and 2, and Fig. 6 is a detailhereinafter referred to.

In the drawings, A, B, and C represent three plates of substantiallythef same shape, and between the plates A and B are located the barrel D'and the lock or firing mechanism, and between the plates B and C islocated the knife-blade E. The barrel D and knife-blade E are bothpivoted upon a bolt d', so that the blade 'E may be swung into its openposition in the usual manner and so that the breech of the barrel D maybe swung out from between the plates A and B to a limited extent, asshown by dotted lines in Fig. 6, in order that a cartridge may beinserted or a shell extracted.

The breech-block F supports the side plates A and B and the back plateG, which is secured at its other end to the block H by means of thescrew g. The block H is formed with a threaded socket in which is fittedthe threaded end of a rod I, and the opposite end of the rod I issecured in a socket in the breechblock F by means of a screw f. The rodI guides the tiring-plunger J, which is moved lengthwise on the rod I inon'e direction by hand and in the opposite direction by the spring j,which bears at one end against the breech-block F and at its oppositeend against the ring-plunger.

To one end of the firing-plunger J is pivoted at j a finger-piece jz,which lies within a slot g2 in the back` plate G and has a projectionextending outside of the stock, which when moved to the rear by thefinger turns the finger-piece on its pivot j', so that it may be graspedby the hand. (See Fig. 6.) The iinger-piece is then moved to the rear bythe hand, and with it the firing-plunger J on its guide I into thefiring position. When inoperative, the finger-piece jg lies within thestock, as shown in Fig. l.

The tiring-plunger J is notched, as atj3j4, and these notches areengaged by the free end of a spring-soar js, which is secured to thebackfplate G by rivets g3. Whenthe firingplunger J is in its tiringposition, as shown in Fig. 6, notch ,i4 is engaged by spring-scarf. Totire the pistol, the sear j is moved out of engagement with the notchL7'4 by means of the trigger K,Which is pivoted on a pin k, fast on theplate B. The inner end of the trigger K isformed with-a slot Zc, intowhich extends a projectionj6 on the free end of the searj. The part k2of the trigger K, which is located at one side of the slot Zc, isyielding, so that as the tiring-plunger J is drawn back by hand v thepart 762 will yield as the free end of the searj5 rides along thefiring-plunger.

On the rod I is a split washer t", the ends of which are separated, andsaid washer is located between the endof the firing-plunger J and thecheck-nut t' andY serves as a yielding abutment against which the end ofthe firing-plunger strikes and to return the firingplunger toitshalf-cocked position. (Shown in Fig. l.)

vThe iiring-plungerJ is provided with an offset or projection f, whichengages the cartridge in the barrel D when the plunger J is A thrownforward by the spring j.

The barrel D is notched on one side at d2 for the spring-catch d3, whichis secured to the breech-block F by the screw d4. This notch and catchserve to lock the barrel D in its closed position. The catch d3 isthrown out of the notch d2 by the pin d5, which is mounted in a socketin the breech-block F and extends through the plate A to the outer sidethereof.

The pin k, on which the trigger K is pivoted, extends through a slot lamin said trigger, and a portion 7622 of the trigger K projects IOOthrough the slot g4 in the back plate G and is formed of a convenientshape to be engaged by the thumb of the operator, and a notch 7c3 isformed in the trigger K at that end which is normally held by a spring7c, located between the block H and trigger K, in engagement with oneend of the slot g4 in the back plate G, as shown in Fig. 6, so that inorder to disengage trigger K from the back plate Gr the trigger must bemoved bodily against the force of the spring 7a4 until the notch k3 ismoved out of engagement With the back plate G, and when this has beendone the trigger K may be swung on the pin lo to disengage searj5 fromthe firing-plunger J and the latter released. 'lhetrigger is normallylocked in a fixed position and cannot be moved to release thetiring-plunger Without first disengaging it from the back plate, andaccidental discharge of the piece is thus prevented.

What I claim as my invention isl. In a firearm the lock above described,comprising a firingplunger; its spring; a notch in the plunger toreceive a yielding sear; that sear; and a trigger with a slot receivinga projection from the sear, and with one'wall of the slot yielding toallow motion of the Sear as the notch in the plunger forces the engagingend of the sear to one side.

2. In a firearm the combination of a firingplunger bored longitudinally;a fixed rod extending through that bore; a spring to throw the plungerforward on that rod; means for moving the plunger on that rod againstthe force of the spring; a Sear for retaining the plunger when in itscocked position; and a trigger for releasing the sear from engagementwith the plunger.

3. In a firearm the combination of a firingplunger; a spring for thatplunger; means for moving the plunger against the force of the spring; asear for locking the firing-plunger; a back plate; a trigger movableendwise and slotted to engage the back plate; a spring to hold thetrigger-slot in engagement With the back plate and thereby prevent thetrigger from being tilted to release the Sear until after the triggerhas been moved endwise and its slot released from the back plate.
